"""Wrapper for mod_fcgid, for use as a CherryPy HTTP server when testing.To autostart fcgid, the "apache" executable or script must beon your system path, or you must override the global APACHE_PATH.On some platforms, "apache" may be called "apachectl", "apache2ctl",or "httpd"--create a symlink to them if needed.You'll also need the WSGIServer from flup.servers.See http://projects.amor.org/misc/wiki/ModPythonGatewayKNOWN BUGS==========1. Apache processes Range headers automatically; CherryPy's truncated output is then truncated again by Apache. See test_core.testRanges. This was worked around in http://www.cherrypy.org/changeset/1319.2. Apache does not allow custom HTTP methods like CONNECT as per the spec. See test_core.testHTTPMethods.3. Max request header and body settings do not work with Apache.4. Apache replaces status "reason phrases" automatically. For example, CherryPy may set "304 Not modified" but Apache will write out "304 Not Modified" (capital "M").5. Apache does not allow custom error codes as per the spec.6. Apache (or perhaps modpython, or modpython_gateway) unquotes %xx in the Request-URI too early.7. mod_python will not read request bodies which use the "chunked" transfer-coding (it passes REQUEST_CHUNKED_ERROR to ap_setup_client_block instead of REQUEST_CHUNKED_DECHUNK, see Apache2's http_protocol.c and mod_python's requestobject.c).8. Apache will output a "Content-Length: 0" response header even if there's no response entity body. This isn't really a bug; it just differs from the CherryPy default."""importoscurdir=os.path.join(os.getcwd(),os.path.dirname(__file__))importreimportsysimporttimeimportcherrypyfromcherrypy._cpcompatimportntobfromcherrypy.processimportplugins,serversfromcherrypy.testimporthelperdefread_process(cmd,args=""):pipein,pipeout=os.popen4("%s%s"%(cmd,args))try:firstline=pipeout.readline()if(re.search(r"(not recognized|No such file|not found)",firstline,re.IGNORECASE)):raiseIOError('%s must be on your system path.'%cmd)output=firstline+pipeout.read()finally:pipeout.close()returnoutputAPACHE_PATH="httpd"CONF_PATH="fcgi.conf"conf_fcgid="""# Apache2 server conf file for testing CherryPy with mod_fcgid.DocumentRoot "%(root)s"ServerName 127.0.0.1Listen %(port)sLoadModule fastcgi_module modules/mod_fastcgi.dllLoadModule rewrite_module modules/mod_rewrite.soOptions ExecCGISetHandler fastcgi-scriptRewriteEngine OnRewriteRule ^(.*)$ /fastcgi.pyc [L]FastCgiExternalServer "%(server)s" -host 127.0.0.1:4000"""classModFCGISupervisor(helper.LocalSupervisor):using_apache=Trueusing_wsgi=Truetemplate=conf_fcgiddef__str__(self):return"FCGI Server on %s:%s"%(self.host,self.port)defstart(self,modulename):cherrypy.server.httpserver=servers.FlupFCGIServer(application=cherrypy.tree,bindAddress=('127.0.0.1',4000))cherrypy.server.httpserver.bind_addr=('127.0.0.1',4000)# For FCGI, we both start apache...self.start_apache()# ...and our local serverhelper.LocalServer.start(self,modulename)defstart_apache(self):fcgiconf=CONF_PATHifnotos.path.isabs(fcgiconf):fcgiconf=os.path.join(curdir,fcgiconf)# Write the Apache conf file.f=open(fcgiconf,'wb')try:server=repr(os.path.join(curdir,'fastcgi.pyc'))[1:-1]output=self.template%{'port':self.port,'root':curdir,'server':server}output=ntob(output.replace('\r\n','\n'))f.write(output)finally:f.close()result=read_process(APACHE_PATH,"-k start -f %s"%fcgiconf)ifresult:print(result)defstop(self):"""Gracefully shutdown a server that is serving forever."""read_process(APACHE_PATH,"-k stop")helper.LocalServer.stop(self)defsync_apps(self):cherrypy.server.httpserver.fcgiserver.application=self.get_app()
